Best Mini PC for Proxmox 2025 – Compact Power for Your Home Lab Setup

If you are looking to run the best mini PC for Proxmox, you are not alone. Mini PCs are increasingly popular among homelab enthusiasts seeking a powerful, compact, and energy-efficient virtualization setup.

In this article, I’ll share my hands-on insights, favorite models that work well with Proxmox, and practical tips for choosing and configuring the right hardware.

Why Choose a Mini PC for Proxmox?

Mini PCs are perfect for home labs:

• Energy Efficient: Most mini PCs has a low power consumption at idle, often under 10W, which makes them ideal for 24/7 operation. They can be more power-efficient than desktop or laptop CPUs.
• Compact Form Factor: They fit anywhere—on your desk, in a cabinet, or even mounted behind a monitor.
• Low Noise: Many models are fanless or use ultra-quiet cooling.
• Cost-Effective: You can get started with virtualization on a budget.

Mini PCs are a popular choice for running home server applications due to their low energy consumption. Whether you’re testing virtual machines, running home automation, or building a high-availability cluster, a mini PC is a smart starting point.

What is Proxmox?

Proxmox VE (Virtual Environment) is an open-source platform for running multiple virtual machines and Linux containers on a single physical computer. It includes a powerful web interface and supports enterprise features like clustering, high availability, and backup scheduling—all without license costs.

It’s an excellent choice if you’re new to virtualization or building a homelab. And because it’s open-source and hardware-flexible, you can run it on everything from repurposed desktops to ultra-compact mini PCs.

Hardware Requirements for Running Proxmox on a Mini PC

Before picking a model, make sure the mini PC supports the following:

• CPU processor with VT-x and VT-d Support: Required for virtualization and passthrough.
• RAM: 8GB minimum for light workloads, 16-64GB for heavier virtualization.
• SSD Storage: NVMe drives is preferred for speed; SATA SSDs are a good secondary option.
• Network Interface: The Intel network chipset is the most compatible choice for virtualization. One of Proxmox’s key advantages is its broad hardware support—it even works well with Realtek chipsets out of the box, unlike VMware ESXi which often requires extra drivers.
• USB Type-C Port (optional): Some mini PCs offer USB-C with DisplayPort or Thunderbolt 4 support, useful for connecting modern displays or fast external storage.
• Connectivity: Most mini PCs include Wifi, but it’s best to disable it or use wired Ethernet. Proxmox doesn’t support Wifi out of the box and expects a stable, wired network interface.

Building a home lab using mini PCs requires careful consideration of both storage and memory capacity. Some models allow dual M.2 drives or room for a 2.5″ SATA drive, making them flexible for running multiple VMs or containers.

Also, check if the BIOS allows enabling virtualization extensions. Some OEMs disable them by default.

Realtek NICs and Proxmox – What You Should Know

Proxmox supports most Realtek NICs out of the box. That’s a major advantage over VMware ESXi, which often requires patched drivers or USB NICs for Realtek-based systems.

If you plan to experiment with ESXi later, choose a mini PC with Intel i225 or i226-V NICs for maximum compatibility. Otherwise, Proxmox gives you the flexibility to use what’s available.

Using dual NICs can improve network performance in a Proxmox setup, especially if you’re planning to isolate traffic (e.g., storage, VM LAN, or WAN passthrough).

Installing Proxmox on a Mini PC: Step-by-Step

Before jumping in, make sure to review the following setup points:

• Download the ISO from Proxmox’s official site.
• Create a bootable USB stick using tools like Balena Etcher or Rufus.
• It’s also a good idea to check if a BIOS version is available.
• Enter BIOS:
• Enable VT-x and VT-d for virtualization support.
• Enable Secure Boot – Proxmox supports it and it helps verify the integrity of your boot process by allowing only signed bootloaders and kernels.
• Enable UEFI Boot Mode, which ensures better hardware compatibility and is required for future-ready configurations.
• Enable TPM (Trusted Platform Module) if available. TPM supports secure encryption and attestation features that can be leveraged in advanced Proxmox setups.
• Boot from USB and follow the guided installation.
• Configure storage using either ZFS (for redundancy) or LVM (for simplicity).
• Assign static IP and create a non-root user.

Note:

Proxmox also supports Secure Boot and TPM inside guest systems such as Windows 11 and modern Linux distributions. If you’re planning to run such VMs, enabling these features in the BIOS ensures compatibility and unlocks full guest OS functionality.

Can You Build a Cluster with Mini PCs?

Absolutely! I run a three-node Proxmox cluster at home using mini PCs. It lets me:

• Migrate VMs live
• Test HA setups
• Use Ceph or NFS shared storage

Just make sure the nodes have matching specs and enough RAM for your needs. Dual-NIC models or SFP+ ports make cluster networking easier.

Why You Should Use 3 or More Mini PCs to Build a Proxmox Cluster

Proxmox really shines when used in a cluster. While a single-node setup works great for testing or light workloads, a true cluster of three or more nodes gives you:

• High Availability (HA): Automatically restart failed VMs on another node
• Live Migration: Move VMs between nodes with no downtime
• Distributed Storage: Use Ceph to create a self-healing, redundant storage pool
• Scalability: Easily add more nodes as your needs grow

Mini PCs make clustering more affordable and energy-efficient. You can run a full Proxmox cluster from your home office or lab with three compact devices and a dedicated switch or VLAN setup. If you’re serious about learning advanced virtualization or simulating enterprise scenarios, starting with a three-node cluster is the way to go.

Final Thoughts – Which Mini PC for Proxmox Should You Choose?

If you’re serious about virtualization, the Minisforum MS-01 is hard to beat. It offers performance, expandability, and enterprise-grade networking in a mini form factor.

For a more affordable start, go with the Beelink SER8 or GEEKOM Mini IT13. They offer enough power for several VMs and make great entry-level Proxmox nodes.

If you’re planning to use ESXi, make sure to check NIC compatibility. Proxmox is much more forgiving in this area.
